Benefits of technology
Enhances data security by ensuring data integrity and preventing modifications or deletions once data is written, even when disk drives are removed, using a standardized interface that maintains security without proprietary dependencies.
Problems solved by technology
When a disk drive is removed from the storage subsystem the data on that disk drive is no longer secure and may be overwritten, deleted or otherwise manipulated.
This puts the integrity of the archived data at more risk than in the past, when the physical nature of the medium provided a natural barrier to the modification of the data.
Furthermore, current WORM systems typically depend on proprietary interfaces to the host computer or disk controller, which may introduce problems with the existing information technology infrastructure.

Embodiment Construction
[0036]Many of the functional units described in this specification have been labeled as modules, in order to more particularly emphasize their implementation independence. For example, a module may be implemented as a hardware circuit comprising custom VLSI circuits or gate arrays, off-the-shelf semiconductors such as logic chips, transistors, or other discrete components. A module may also be implemented in programmable hardware devices such as field programmable gate arrays, programmable array logic, programmable logic devices or the like.
[0037]Modules may also be implemented in software for execution by various types of processors. An identified module of executable code may, for instance, comprise one or more physical or logical blocks of computer instructions which may, for instance, be organized as an object, procedure, or function. Nevertheless, the executables of an identified module need not be physically located together, but may comprise disparate instructions stored in d...

An apparatus, system, and method are disclosed for writing data to protected partitions of storage media. The apparatus includes a control module configured to communicate with a host device and receive write commands for a storage device, a parse module configured to extract logical block addresses, a check module configured to verify a protection state, and a protection module configured to allow write commands according to the protection state. The system includes a host device, a storage device coupled with the host, the storage device comprising an enclosure having storage media and a control module, and the apparatus. The method includes communicating with a host device and receiving write commands for a storage device, extracting logical block addresses from the write commands, verifying a protection state of the extracted logical block addresses, and allowing write commands according to the protection state of the extracted logical block address.
Description
BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]This invention relates to storage media and more particularly relates to implementing protected partitions in storage media.[0003]2. Description of the Related Art[0004]The explosion of data created by e-business is making storage a strategic investment priority for companies of all sizes. As storage takes precedence, a major concern has emerged: the need to archive data in a non-rewritable and non-erasable manner. This need is based in part on the need to meet the legal requirements of the management of financial data, such as required by the Securities and Exchange Commission and HIPPA, as well as the archival of court records, customer records, and other long-lived information. Traditionally, optical media has been used to store date in non-rewritable and non-erasable form. Non-rewritable and non-erasable data may also be referred to as reference data, fixed content data, or Write Once Read Many (WORM) data.[0005]Inf...
